The sliver passing from the dofier is 44 of Figure 2, 5 adapted to engage through the horizontally elongated trumpet 24 and is then adapted to enter the drawing rollers to be hereinafter described.

A pair of upper and lower rear drawing rollers 26 and 21 are disposed forwardly of the trumpet supportingplate 22 and the roller 26 is formed with trunnions 28 and 29 at the opposite ends thereof which are journalled in'vertically slidable bearings 30 and 3|. The bearing 36 is vertically slidable in an upright bearing guide member 32 and the bearing 3| is vertically slidable in an upright bearing guide 33.. The lower roller 21 is mounted on a roller shaft 34 which is rotatably mounted in the guides 32 s and 33. The shaft 34 is journalled through the bearing guide 32 and the shaft 34 is also journalled inthe bearing guide 33. The-bearing guide 33 as shown in Figure 4 is provided with an upwardly opening shaft bearing 35 formed with an arcuate lower portion within which the shaft 34 rotates. The guide 32 is similar in every detail to the guide 33.

A pair of upper and lower intermediate rollers 36 and 31 are disposed forwardly from the rear rollers 26 and 21 and the roller 36 is formed with trunnions 38 and 39 which are rotatable in bearings 48 and 4| respectively. The bearing 40 is vertically slidable in a bearing guide 42 which is secured in upstanding relation to the baseplate l9 and th bearing 4| is vertically slidable in a bearing guide 43 disposed forwardly from the bearing guide 33 and mounted in upstanding relation on the base plate-|9. The guides 42 and 43 are similar in every detail to the guide 33 shown in Figure 4 and the lower I roller 31 is mounted on a roller shaft 44 which is rotatably carried by the bearing guides 42 and '43. A pair of front upper and lower rollers 45 and 46 respectively are disposed forwardly of the intermediate rollers 36 and 31 and the roller 45 is provided with trunnion's 41 and 48 which are journalled in bearings 49 and 58 respectively.

The bearing 50 is vertically slidable in a bearing guide 5| disposed forwardly of the guide 42 whereas the bearing 50 is vertically slidable in a bearing guide 52. The guides 5| and 52 are similar in every detail to the guide 33. The roller 46 is mounted on a roller shaft 53 which is journaled through the lower portion of the guide 5 and the lower portion of the guide 52.

The base plate H! is formed on the upper side thereof with a longitudinalchannel or keyway 54 and also with a second longitudinal channel or keyway 55. The bearing guide 33 on the lower end thereof is formed with a key 56 engageable in the keyway and adjustable lengthwise of the keyway 55. The bearing guide or support 33 is secured in adjusted position lengthwise of the keyway 55 by means of a bolt.

51. The lower end of'the bearing guide 43 is also formed with a key 58 engaging in the keyway 55 and the lengthwise adjustment of the guide 43 is accomplished by means of a fastening device 59. The lower end of the bearing guide or support 52 is formed with a key 60 engageable in the keyway 55 and the guide 52 is secured in the keyway 55 by means of a fastening device 6|. In practice the forward guide 52 is nonadjustable in the keyway 55, whereas the two guides 33 and 43 are adjustable relative to each other and also to the guide 52. The guides 32, 42 and 5| are also adjustable lengthwise of the keyway 54 by means similar to the. means shown in Figure 4 with respect to the guides 33.

43 and 52.

a stationary bearing 64 and each of the bearings 62, 63 and 64 is provided with a depending key engageable in a keyway 65 carried by the upper side of the base plate IS. The bearings 62 and 63 and the bearing 64 are secured relative to the plate l9 by fastening devices 66. The plate I9 is formed Within the keyway 55 with an elongated slot 61 through which the fastening members 51, 59 and 6| are adapted to engage. The plate l9 is also formed with an elongated slot 68 within the keyway 54 through which the fastening members 69 engaging the bearing guides 32, 42 and 5| are adapted to extend. The base member I9 is also formed with a third elongated slot 19 within the'keyway 65 through which the fastening members 66 are adapted to engage. The shaft 34 has'fixed thereto a gear'1|. Shaft 44. has fixed thereto a gear 12. The shaft 53 has fixed thereto a gear 13 and also has hired thereto a second gear 14. A vertically disposed gear train supporting plate 15 is secured in upstanding relation to the base plate |9 by fastening devices 16. A gear 11 is rotatably' mounted V so that the shaft 18 may be secured in the de-\ sired position along the length of the arcuate slot 88. The gear 11 meshes with the gear 13 and also meshes with the gear 12. stub shaft 8| extends inwardly from the plate 15 and has rotatably mounted thereon a pair of gears 82 and 83. The two gears -82'and 83 are fixed relative to each other, but are rotatable on the shaft 8|. The shaft 8| is formed with a reduced outer end'portion 84 extending through an arcuate slot 85 which isformed in the plate 15. reduced stub portion 84 so that the shaft 8| can be tightly secured in adjusted position to main tain intermeshing of the gear 82 with the gear 12 and intermeshing of the gear 83 with the gear 1 I.

An idler or intermediate gear 81 is rotatably mounted on a stationary shaft 88 which is secured by a fastening member 89 through the rear portion of the plate 15. The gear 81 meshes with the gear 14 and also meshes with a driv-- ing gear 90 mounted on a driving shaft 9|. In

practice the shaft 9| is the coiler shaft forming a part of the present mechanism of the carding machine.

In order toprovide for cleaning'of the bottom contact with the rollers 21 and 31 by means of a pair of flexible suspension members 93. The

- suspension member 63 is extended about the .ad-

jacent ends of the roller 31 which are reduced slightly in diameter as at 94 and 'one end of the flexible member 93 is extended through an opening'95 formed in the plate or cleaning member 92. An enlargement 96 is formed on the'lower end of the flexible member 93 below the plate 92. The plate 92 is formed on the opposite longitudi- A second A nut 86 is threaded onto the The' nal edges thereof with outwardly opening slots 91 through which the flexible member 93 loosely engages and the base plate I9 is also formed with vertical openings 98 through whichthe flexible member 93 passes.

The free lower end of the flexible member 93 which extends below the plate I9 has secured thereto a weight 99. The plate 92 is formed with an arcuate concave channel I below the roller 46. and preferably, the roller 46 is disposed out of contact with the concave cutout I 09. By suspending the cleaning member 92 through the medium of the flexible members 93 and weights 99, the cleaning member 92 will be held in frictional contact with the rollers 21 and 31 so that any fibers clinging to these rollers will be removed and will not be permitted to accumulate on these rollers and periodically intermingle with the fibers of the sliver passing between the upper and lower rollers.

A forward trumpet IOI is supported from an upstanding supporting bar I02 which is secured by fastening members I93 to the frame member IT. The forward trumpet I0] is of forwardly divergent configuration and is formed in the upper side thereof with a longitudinal passage or slot I94. The slot I04 permits the positioning of the sliver in the trumpet IIlI after the sliver has passed through the drawing rolls and before the sliver enters the rolls I5 and I6.

In the use and operation of this attachment, the attachment is secured by the fastening members 2| to the carding frame member I1. The gear 90 is mounted on the coiler shaft 9I' so that the gear train will be operated from the coiler shaft 9I. The sliver is initially passed through the rear horizontally elongated trumpet 24 and then passed through the drawing rollers 26, 21, 36, 31, 45 and 46. The drawing rollers will draw out the fibers of the sliver and parallelize these fibers before the sliver enters the carding machine rollers I5 and I9. The pairs of drawing rollers 2B, 21 and 36, 31 may be adjusted relative to each other and to the rollers 45 and 46 depending on the length of the particular cotton fibers which form the sliver.

The adjustment of the pairs of drawing rollers will provide for a more even sliver and a better parallelizing of the fibers than is possible with non-adjustable rollers. This attachment can be mounted on the present carding" machine frame without any change in the construction of the frame, it being only necessary to provide openings in the frame plate IT to receive the fasten-' ation of the rollers in any adjustment thereof and these rollers may be adjusted to provide for the desired space between the contacting surfaces of the pairs of rollers to accommodate the particular. fiber lengths passing between the drawing rollers.

This attachment will eliminate the necessity of passing the sliver through a separate drawing frame and will speed up the handling of the sliver as the drawing operation takes place during the passage of the sliver from the doffer to the calender rollers and before the sliver enters the coiler.

What we claim is:

In a drawing attachment for interposing between the calender and doifer rollers of a carding machine, said attachment comprising an L- shaped support having one side thereof horizontal and another side thereof vertical, means securing said vertical side to the machine, said horizontal side having a plurality of parallel channels in the upper side thereof and also having elongated slots in the bottoms of said channels, front, rear and intermediate pairs of rollers, a shaft for each roller, bearings for said shafts engaging in said channels, gears on certain of said shafts, means engaging through said slots whereby said bearings may be adjusted lengthwise of said channels, gears secured to said shafts, a vertical plate fixed at one end of said support and having a pair of arcuate slots therein, a pair of stub shafts adjustably mounted in said slots, and idler gears on said stub shafts and meshing with certain of said other gears whereby said rollers may be operated in any adjustment of said bearings.
